I have the following list
data = { {11, {121, 122}}, {21, {221, 222}}, {31, {321, 322}} };
>From each sublist, I want to extract the first element and the second
element of the second sub-sub-list that is:
wanted_result={ {11, 122}, {21, 222}, {31, 322} }
I tried
data[[All, {1, {2,1}}]]
but it gives me error.
What is the right selector ?
